After examining its design, cooling capabilities, and build flexibility, it's clear that darkFlash has created a chassis that targets both aesthetics and functionality.

C280 E-ATX PC Case Pillar-less dual glass design provides a seamless 270° panoramic view Supports back-connect motherboards for a clean, cable-free aesthetic Features native vertical GPU mounting to showcase your graphics card Accommodates up to ten fans and 360mm radiators for superior cooling

First Impressions

The first thing you'll notice about the darkFlash C280 is its pillarless dual-tempered glass design. The seamless 270° panoramic view creates a clean and modern look, allowing your components to become the centerpiece of your setup. Whether you're showcasing RGB lighting, custom cables, or a flagship graphics card, the C280 provides an unobstructed display from multiple angles.

Unlike many panoramic cases that sacrifice airflow for appearance, the C280 features a six-sided ventilation design that helps maintain efficient cooling while preserving its premium visual appeal.

Build Quality and Design

The C280 is constructed from 0.7mm SPCC steel and feels solid and durable during assembly. The tool-free quick-release panels make installation and maintenance remarkably easy, allowing builders to access internal components without unnecessary hassle.

Key design highlights include:

• Seamless 270° panoramic tempered glass
• Tool-free removable panels
• Native vertical GPU mounting support
• Support for back-connect motherboards
• Modern cable management layout

The support for back-connect motherboards is especially noteworthy. As more motherboard manufacturers adopt rear-connector designs, the C280 is ready to deliver an ultra-clean, cable-free appearance.

Cooling Performance

Cooling is where the darkFlash C280 truly shines.

The chassis supports up to 10 fans and multiple radiator configurations, giving builders tremendous flexibility for both air-cooled and liquid-cooled systems.

Fan Support

• Top: 3 × 120mm or 2 × 140mm
• Side: 3 × 120mm
• Bottom: 3 × 120mm or 2 × 140mm
• Rear: 1 × 120mm

Radiator Support

• Top: Up to 360mm
• Side: Up to 360mm
• Rear: 120mm

This layout allows builders to create highly optimized airflow configurations, making the C280 suitable for gaming systems equipped with powerful CPUs and GPUs.

During high-load gaming sessions or content creation workloads, the extensive ventilation and fan support help maintain stable temperatures while keeping noise levels under control.

Hardware Compatibility

One of the biggest strengths of the C280 is its generous hardware clearance.

The case supports:

• E-ATX, ATX, Micro-ATX, and Mini-ITX motherboards
• GPUs up to 420mm in length
• CPU coolers up to 155mm in height
• 3 SSDs and 2 HDDs
• Vertical GPU installation support

The 420mm GPU clearance is particularly impressive, allowing compatibility with virtually every modern flagship graphics card on the market.

Builders planning to install large RTX 5090, RTX 5080, or Radeon flagship cards will appreciate the extra room available inside the chassis.

Building Experience

The overall building experience is beginner-friendly while still offering the flexibility that experienced enthusiasts expect.

The spacious interior makes cable routing straightforward, while the removable panels simplify component installation. The support for rear-connect motherboards further reduces cable clutter, resulting in cleaner builds with better airflow.

For users upgrading from traditional mid-tower cases, the difference in workspace and accessibility is immediately noticeable.
